This video is from my first run this morning. The struts were parallel with the rear ride pads. The boat was carrying four 3S 5000mah packs. Two as far forward under the deck as possible and two behind them (all in the battery trays made for this size battery). I was thinking that the weight of four batteries would eliminate the bouncing. Is it possible that I'm measuring strut height/angle incorrectly? I've been putting a straight edge on the rear ride pad and comparing the strut angle to that.

Arrower, that definitely looks like a CG/setup issue.
I posted this back in page 3. Make sure you measure as shown in this picture, not just off the rear pad as it is angled and will give you a false measurement. I use a setup board to set the boat on and measure the distance from the board to the strut. I find it easier than using a ruler. Notice the black runs the length of 2 pads.
Agreed. Most every video, other than the one where I'm running laps, has been done with just 2 packs and you will notice the boat doesn't bounce.
The manual explains how to check and adjust your struts. It says to use a ruler to measure to make sure they are level. Here is a picture to help. The distance between the hash marks should be 4mm to 3.75mm. The ruler is represented by the black line. It must lay across the middle and rear pad and extend past the strut.

Thanks Rafael. I did see that picture before but I didn't take note of the importance of using multiple pads as the reference point. Thank you for the help. I hope you don't think I was trying to blast ProBoat. I was fully aware that it was a setup issue and not a product issue. That video is unlisted on youtube so it will only show up here. So, do you lay your boat on a flat surface and measure the strut from that surface? When I do that, the front sponsons lay flat on the counter, the middle pads are off the surface, the boat is resting on the water intakes, and the back edge of the rear pad is maybe .25-.5mm off of the surface. Is that the correct position to measure strut height from or do I need to put something under the boat to support only the rear two pads?Comment

You bring up a valid point. The water pick ups are in the way if you rest the boat on a table. I forget my setup board is drilled so the water pick ups sit in the holes and the boat sits flush. The way it's explained in the manual is to use a long enough ruler across the rear two pads, making sure the ruler extend past the struts. The ruler would be represented by the black line and the water pick ups would not be in the way.
I'll go back and edit my post regarding placing it on a table. Thanks for catching that.
I didn't take your post in any other way that you trying to tune your boat and then showing me what it was doing.Rafael Lopez

Some snaps from yesterday at the lake. We had lots of fun & were there for about 2.5 hours. I have some footage from the drone Im working on editing now. These were taken with my camera but not buy me. I was busy flying on and off the water, no wipe outs. I didnt have a gps, but The Zelos was easily doing over 70mph with the other props on 22.2v. Like a boss. I just did a few runs then put the stocks back on. Everyone that stopped Including the cops said that "yellow boat" caught their attention.

Sweet, great pictures!! I have no doubt that the stock electronics can handle aftermarket props, within reason. Especially if you go down 1 click on timing, instead of going up. The electronics have plenty of hear room considering stock amperage consumption is relatively low.
What props are they, BTW?Rafael Lopez

Also wondering if the stock props are cast or machined. I hate balancing props so I wanna order a set of CNC counter rotating same size as stock or maybe a hair larger. Was thinking the counter rotating 4314's if the stock ones are 42mm.Comment

I set the struts at 4mm like Rafael described and the speeds came way up. 63.2mph with two 3S packs all the way forward and unsharpened stock props. I swapped to an identical set of fully charged packs and ran them with another set also in the boat just for added weight (same power configuration, just more weight) and it ran 54.7mph. I removed the extra batteries (still running the partially depleted second set of batteries) and the speed came up to 58.2mph and the LVC kicked in shortly after (whoops). Thanks again for the help Rafael. The boat still bounces the same way all the time but the speeds are where they should be. One time in two sets of packs it stopped bouncing at full speed and looked planted at the same time. I think it might have been when I headed into a little breeze but I'm not positive. Anyway, fun times at the lake!
